Hi,
I have a requirement where I need to export DB dumps using DBMS_DATAPUMP api to the Object storage on Oracle Cloud Infrastructure.

I found below statement on official document to export dumps at object storage using expdp utility.

expdp admin/password@ADWC1_high \
     filesize=5GB \
     dumpfile=default_credential:https://objectstorage.us-ashburn-1.oraclecloud.com/n/namespace-string/b/bucketname/o/exp%U.dmp \
     parallel=16 \
     encryption_pwd_prompt=yes \
     logfile=export.log \
     directory=data_pump_dir

But I didn’t get any reference for DBMS_DATAPUMP api, Could you please help me to know how to perform same task using DBMS_DATAPUMP api.

Sorry, I'm not able to find any official documentation on this either! I'm following up internally.

If you're using ATP, you can use dbms_cloud.export_data to copy data to the object store as shown in this guide:

https://docs.oracle.com/en/cloud/paas/atp-cloud/atpug/export-data-select.html#GUID-7DAB00F6-65B8-4678-B222-7939001A3469

Though note the files generated by this are incompatible with impdp - you need to use dbms_cloud to import them or external tables using the oracle_datapump driver.

Export dumps directly on Object store.

We are still looking for the feature that will export dump files directly to the Object store using DBMS_DATAPUMP api. Could you please let me know if you have any update on this.

Documented in 21c using the constant DBMS_DATAPUMP.KU$_FILE_TYPE_URIDUMP_FILE
and since the constant exists in 19c I'd suspect it works there too

Thanks for the reply!
Actually I tried the example that will export dump file directly to the Object store but getting below error and not sure why am I getting this even after correct URI for bucket and Credential.
Error:

Actually we are working on FA SaaS application that uses ATP database 19c(19.5). Could you please confirm which DB version supports feature of exporting dumps directly to the object store using DBMS_DATAPUMP api.
